OF ELMIRA, NEW YORK.

ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 679,465, dated July 30, 1901.

Application filed September 19,1900. Serial No. 30,492. (No model.)

.To all whom, it may concern,.-

Be it known that I, ALEXANDER P. MoR- ROW, a citizen of the United States, residing at Elmira, in the county of Ohemung and State of New York, have invented certain new and useful Improvements in Roller-Bearings for Bicycles, duc.; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to improvements in roller-bearin gs; and the object is to provide an adjustable antifriction-bearing of simplified construction and wherein the antifriction-rollers and their associated holding and bearing elements are held in coacting relation and disposition without liability of end thrust, distortion, or displacement.

With this object in view the invention consists in the novel construction and arrangement of parts and their combination, as will be hereinafter fully disclosed and specified, and particularly as will be pointed out and distinctly claimed.

I have fully and clearly illustrated my improvements in the accompanying drawings, to be taken as a part hereof, and wherein- Figure lis a longitudinal central sectional view showing the invention as applied to the hub and axle of a vehicle, the race or annular channel between the bearing-sleeves being of a contour adapted to receive roller-bearings composed of double conical sections joined at their bases. Fig. 2 is a detail side view of a roller-retaining ring or sleeve of the contour adapted to receive and hold the It will be premised that the invention is applicable to all constructions wherein it is requisite and desirable to mount a revoluble element on an independently-rotatable support; but, as is apparent, the invention is especially adapted for uses in mounting the hubs of all kinds of road-vehicles on their axles, such as buggies, velocipedes, and motor-vehicles or automobiles.

Referring to the drawings, Fig. l, A designates an axle or shaft carrying on its opposite ends or at the end portions duplicate constructions of my improved rollers, the disposition or arrangement of the elements being merely in reverse relation, so that the description of one refers equally to the construction of both, and similar letters and numerals refer to like parts and elements in each. The ends of the shaft or axle are screw-threaded, as at l, to receive any suitable fastening means whereby the adjustable elements may be held in the desired set or fixed position against endwise displacement. On the shaft A at each end is mounted a sleeve or cone 2 2, cored out and screw-threaded to lit the screw-threads of the shaft. The outer end of eachof the cone- Sleeves 2 may be formed with an annular iange or collar 3, adapted to close the end of the hub and constitute a closure to exclude the entrance of dust to the interior. The cones 2 at their inner ends are formed with inclines 4 5, arranged on different planes and coincident with the reverse conical sections of the roller-bearings, as indicated in the drawings. The sleeves or cones 2 are, by reason of their threaded connections therewith, adjustable on the shaft or axle.

B designates the boxing of a wheel, which may be of any ofthe approved exterior styles or constructions, the interior being a true cylinder, at least at the end portions, which are preferably provided with interior screwthreads, as 6 6, which are adj ustably engaged by cone rings 7 7, having their inner bearingsurfaces formed with inclined bearing-planes 7 8, reversely disposed to the inclined surfaces of the cones on the shaft, so that an annular race or channel is formed between the cones and ring, the bearing-surfaces of which are in agreementwith the bearing contour of the rollers 12. To retain and hold the rollers in their proper positions, a retain'- IOO ` and arrangement.

ing-ring C is provided, which -is arranged between the cone ring and cone, setting over the latter, as shown, the exterior and interior of the roller-retaining ring C being substantially in agreement and made to conform to the contour of the walls of the race and to the bearing-faces of the rollers. At the respective ends of the retaining-ring are formed annular anges 8 9, wherein are made radial notches 10, arranged at determined distances apart and constituting bearings for the pintles or arbors of the rollers, and in the wall g of the roller-retaining rings are formed openings ll, into which the roller-bearings project, but do not protrude beyond the inner surface.

l2 designates the rollers, which consist of two sections or frustums of cones united either at their frustums or atl their bases, 4according to the style used, that in Fig. l being double cones united at their base and that in Fig. 3 being double cones united at their f'rustums. The rollers in each style or shape are arranged in their bearings so that the greater portions project .above the outer surface of the retaining-rings in order that they will run on and bear upon the surfacel of the lcone rings of the hub.

By reference to Fig. 3 of the drawings it will be perceived that the cone ring, the inner cone, the retaining-ring, and the rollers are of reverse bearing contours to that of the similar elements shown in Figs. l and 2, the object being in both forms that a race and retai'ni'ngring are provided, whereby the rollers are held against endwise thrust and the whole is held in adjustable disposition cisely identical with those of the varied construction, shown in Figs. l and 2 and involve identical functions.

To assemble the parts,the cone ring is fitted in :the boxing to the position desired. The retaining-ring,with the rollers arranged-therein, can then be placed in position on the coneA ring, the shaft can then be passed throughA the `hub and retaining-ring, the cone can then be screwed down on the retaining-ring, and a l fastening-nut is to be screwed up in place. The elements at the opposite end of the hub may then be assembled and secured, as indi? cated.

What vI claim is- W 1. Ina roller-bearing, an outer ring having double conical surfaces, an innerv ring or cone having double conical surfaces, a .retainingring, and rollers in the retaining-ring having reversely-arranged conical bearing-surfaces to run on the double conical surfaces of the outer ring, substantially as described.

2. In a roller-bearing, the combination with an axle, a double conical ring on the axle, a hub, and a double cone ring on said hub, of rollers arranged between the said rings and formed with double 4conical surfaces, substantially as described. v

3. In a roller-bearing, the combination of 'an axle, provided with a cone sleeve, a retaining-ring fitted to said cone sleeve, rollers formed with reversely-arranged double conical bearing-surfaces and journaled in the retaining-ring, a hub, a cone ring adjustable within the hub and formed with double conical bearing-surfaces engaged by the double conical rollers, substantially as described.

4. In a roller-bearing, the combination of a shaft or axle formed with exterior screwth reads, a cone sleeve adjustable on the shaft, a retaining-ring on the shaft and cone sleeve, rollers journaled in the retaining-ring and formed with reversely-disposed conical bearing-surfaces, a cone ring having coincident conical bearing-surfaces engaged by the double cone rollers, and a hub within which the cone ring is adjust-ably secured, substantially as described.

5. In a roller-bearing, the inner cone having doubleconical bearing-surfaces, a retaining-ring formed with end flanges having bearings formed therein and a conical body between the flanges, a ring secured to the hub having double conical bearing-surfaces,

and rollers journaled in the said retainingring, substantially as described.

6. In a roller-bearing, the combination of a shaft, cones or sleeves ou the shaft having conicalinner faces, retaining-rings on the said cones or sleeves formed with flanges at their ends and bearings on the flanges, rollers journaled in the flange-bearings and formed with double reversely-disposed conical bearingsurfaces, a hub, and cone rings in the hub having double conical bearing-surfaces coincident with the surfaces of the double cone rollers, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.
